Abstract

Polycrystalline samples of Eu(Ni1-xCux)(2)P-2 (x = 0.00, 0.05, 0.10, 0.15 and 0.20) were investigated by x-ray diffraction (XRD), scanning electron microscopy (SEM), electrical resistivity p(T) and magnetic susceptibility x(T) measurements. XRD and SEM results confirm essentially single phase nature of the samples. The substitution of Ni by Cu atoms leads to dramatic change in the behavior of p(T) of EuNi2P2 where Kondo coherence is destroyed even for x = 0.05. A minima in the p(T) has been observed for all doping concentrations. This behavior has been discussed in terms of Kondo effect.
